Abstract
An electrophotographic copying machine includes a paper feeding tray and a paper discharging tray respectively attached to both end surfaces of a body, each of which has a first, a second and a third tray plates which are rotatably connected to each other. When the machine is not used, the first, second and third tray plates are contained in the body in a state where the same are collapsed and folded over each other and, when the machine is used, the first, second and third tray plates are withdrawn and developed. A plurality of ribs which are extended in a paper feeding direction are on one upper surface of the first plate attached to the body in a rotatable manner, and a plurality of through holes, or slits, which receive the ribs when the first, second and third tray plates are collapsed are formed on the second and third tray plates.
